1 Introduction
1.1 Background of the Project
In recent years, with continuously rapid development of urban economy of Nanchang,
the urban area is expanded and the population increases continuously, and with the
single-center urban development mode, centripetal radialized traffic flow is formed,
which causes severe traffic jam in downtown area and inconvenient connection with
peripheral areas, and the condition that “traffic jam and inconvenient to cross over the
Ganjiang River” is serious, traffic supply and service level directly affect the new
round construction and development of Nanchang. In order to get rid of the current
traffic problem and prevent future traffic crisis, the municipal government absorbed
successful experiences on solving traffic problems from domestic and abroad big
cities, and determined to vigorously develop a public transit with rail transit being
backbone and ground traffic being major means of transportation, thus study and
planning for rail transit come to consideration. Nanchang City Planning (2001-2010)
involves the planning of construction of 5 rail transit lines and puts forward the
implementation plan of construction of line 1 and line 2 phase 1 project within the
planning period.
In January 2008, based on Notice on Strengthening Construction and Management of
Urban Rail Rapid Transit of the General Office of the State Council (GBF [2003] No.
81), Nanchang has entrusted Shanghai City Comprehensive Transportation Planning
Institute with The Plan of Nanchang Urban Rail Transit Network. In July 2008, the
planning was completed and was approved by people’s government of Nanchang in
file HFTZ (2008) No. 163. The network planning scheme involves 5 lines with total
length being 167.7km, and there will be two comprehensive vehicle bases, two
periodically repair sections and three parking lots.
The plan is to construct Line1 phase 1 project and Line 2 phase 1 project between
2009 and 2016, and construct the X-shaped skeleton network composed of Line 1
phase 1 and Line 2 phase 2 in 2016. We will construct Line3 and the second phase of
Line 1 and Line 2 between 2016 and 2020, and form the rail transit skeleton network
composed of Line 1, Line 2 and Line 3 by 2020. The whole network will be gradually
completed from 2020 to the vision years.
According to the network planning revision, Shanghai Tunnel Engineering and Rail
Transit Design and Research Institute and Shanghai City Comprehensive
Transportation Planning Institute co-compiled the Nanchang Urban Rail Rapid
Transit Construction Planning (2009-2016); in July 2009, the planning was approved
by National Development and Reform Commission in FGJC (2009) No. 1978 Notice
on Printing and Distributing the Reply of NDRC on Immediate Nanchang Urban Rail
Transit Construction Planning (2008-2016) (attachment).
According to the planning, a rail transit project with length being 50.6km will be built
from 2009 to 2016, which includes line 1 phase 1 project and line 2 phase 1 project.
Of which, the total length of Nanchang Rail Transit Line 2 Phase 1 Project will be
about 23.78km, and there will be 21 stations which will all be underground stations
with average station spacing being about 1.09km. The whole line is set with a
comprehensive base which locates at southwest of South Avenue Station.
The project is from Nanchang West Railway Station to Xinjiaan Station, the route will
go through the west railway station planning area, the Hongjiaozhou district, the
Honggutan new district, the center of the old town and the eastern district of the city,
and it will connect the Nanchang west railway station, the International Sports Center,
the College Town of Honggutan, the Nanchang Central Business District, Yangming
Road, Bayi Square, Nanchang Railway Station and some other passenger hubs, which
not only connects the core areas of old town and new town, but also covers the most
important area of south-north corridor between Changnan old town and Changbei new
town.
In February 2010, Nanchang Rail Transit Co., Ltd entrusted Guangzhou Metro Design
and Research Institute Co., Ltd with compilation of Nanchang Rail Transit Line 2
Phase 1 Project Feasibility Study Report (February,2010), which is also the design
consideration for Environmental Impact report.
Meanwhile, Environmental Impact Report on Nanchang Rail Transit Line 2 Phase 1
Project which was compiled by China Railway Forth Survey and Design Institute
Group Co., Ltd under entrustment of Nanchang Rail Transit Co., Ltd was submitted to
Ministry of Environmental Protection for approval; in September 2010, Ministry of
Environmental Protection gave official reply to the environmental impact assessment
in HS(2008) No. 284 Reply of the Nanchang Rail Transit Line 2 Phase 1 Project
about the Environmental Impact Report and approved the construction of line 2 in line
with measures listed in Environmental Impact Report.
Nanchang Rail Transit Line 2 Project was listed in World Bank Loan Project in 2012,
and files such as Environmental Assessment Report (EA) and Environmental
Assessment Summary and Management Plan (ESMP) which meet the World Bank’s
requirements shall be compiled, after being entrusted, through field research and
relevant information and data collection, we organized experienced environmental
assessment personnel and made supplement and improvement for contents including
social impact assessment, cumulative impact assessment, alternative solution analysis,
risk analysis, ESMP, immigrant relocation and arrangement and public participation etc
which are concerned by the World Bank based on the original environmental impact
assessment report approved by the Ministry of Environmental Protection. The
compilation of this report was completed in September 2010.

be not carried out in case of dry weather with air pollution index above 100, or strong
wind above level 4. In case of air pollution index between 80-100, cleaning shall be
carried out every 4 hours with alternative of sprinkling and cleaning. And denser
cleaning shall be carried out in case the air pollution index is larger than 100.
(5)Transport Vehicle
Due to the large project scale, especially transport of large quantity of deserted earth
and construction materials during shield tunneling, the passage of a large number
construction vehicle will form pressure on the urban roads in surrounding areas. Thus
the construction unit shall rationally organize vehicle flow to reduce traffic pressure,
and shall report the conventional vehicle flow, running routes and time section to the
traffic management department, and shall avoid traffic peak time. Inform the traffic
management department in case of rush transport or transport of long and large
components so as to organize forces to evacuate traffic.
(6)Domestic Rubbish
The domestic rubbish on the construction site shall be piled in bags on appointed sites,
and handed over to the urban environmental health department for disposal. The
dinning and kitchen rubbish produced in the catering industry and dinning room shall
be entrusted to the cleaning enterprise for separate collection, transport and disposal.
It is forbidden to hand over such rubbish to other unit and individuals.
(7)Project Completion and Acceptance

protection projects according to the methods for completion acceptance of
environmental protection projects of construction project before project completion
and formal operation.
(8) Environmental Monitoring during Construction Period
①The construction unit and relevant government departments shall entrust special
personnel to trace and investigate land requisition and resettlement during
construction period to learn about information on the resettled personnel and form a
written report;
②The full-time(part-time) environmental protection staffs of the construction unit
shall urge the construction department to implement various environmental protection
measures during construction period, and take charge of construction management
and completion acceptance of the environmental protection facilities of the unit. The
environmental supervisors shall inspect various monitoring items during construction
period according to the design document and construction progress, and report
implementation of monitoring items to the higher authority regularly(every month).
Monitoring over social, economic and environmental impacts shall be carried out by
the environmental protection department in the locality of the project.
3.4.3 Environmental Management during Operational Period
Environmental management during operational period is a long-term management
work, and perfect management organ and system must be established, and various
environmental supervision and management system shall be established based on that.
Strengthen environmental management during project operational period, and ensure
normal operation and assessment of various environmental protection facilities; It is
proposed that the operational company shall be equipped with 1 to 2 full-time
environmental protection managerial personnel. Duties of full-time environmental
protection personnel: take charge of environmental management of the whole
company and external environmental management; do well in education and publicity
to improve the awareness of environmental protection and technical levels of
managerial personnel and staffs at various levels; formulate environmental
management methods and operational regulations for pollution prevention and control
facilities during operational period of the rail transit, regularly maintain, inspect and
repair sewage treatment equipment, and noise control measures for air kiosks etc. to
guarantee normal operation thereof. Cooperate with the environmental protection
authority in environmental management, supervision and inspection; cooperate with
the environmental protection authority in disposal of various environmental pollution
accidents etc.
According to the characteristics of environmental impacts of the project and the
assessment results of the report, the key points in environmental management during
operational period of the project are as follows: noise monitoring and management for
the environmental control equipment of the underground stations and noise in other
sections; monitoring and management of the impacts on the environmental quality by
the vibration of the train in underground sections along the project line; management
of the depots and comprehensive drainage facilities on the base, and monitoring of the
disposal effect; The aforesaid three aspects are the fields that tend to cause pollution
accident and environmental disputes, and special attention shall be paid thereto.
4 Environment impact assessment and measures of
Prevention and mitigation
4.1 Conclusions of Environment impact assessment
4.1.1 Predictive Assessment of Acoustic environment
Phase I project of Nanchang Rail Transit Line 2 starts from South Zhanqian Avenue
Station and ends at Xinjiaan Station, runs through central urban area of Nanchang
with “n”-shape, and passes West Station planning area, Hongjiaozhou District,
Honggutan new district, old urban central area and Chengdong District etc. The whole
line adopts underground laying and mainly runs along areas under present arterial
streets such as Fenghe Avenue, Yangming Park and Bayi Avenue, so traffic noise is
the main noise source of areas along the line and the main reason why environmental
noise at partial areas along the line exceeds the standard; the noise of social activities
is the second largest noise source.
Section from Nanchang West Station to Hongguzhong Avenue Station is located in
Honggutan new district, sensitive points are slightly affected by road traffic noise and
social activity noise, so acoustic environmental quality is good; the section from
Yangming Park Station to Xinjiaan Station is located in old urban central area, the
surrounding area of stations is characterized by dense population, developed
commercial activities and large traffic flow of motor vehicles, so it is greatly affected
by road traffic noise and social activity noise.
(I) Construction period
The noises during construction period mainly come from open-cut construction of
underground station (including civil construction of station entrance/exit and air shaft),
civil construction of car depot and integrated base; it is mainly from the operation
noises of various construction machines, such as road breaker, excavator, bulldozer,
air compressor and etc, and also the noises of various construction transport vehicles
and noises of building demolition and breaking works of existing road.
During independent construction of construction machines, at earthwork phase, the
noise 40m away from sound source can meet daytime standard in construction site of
75dB(A); at foundation stage, the noise 30m away from sound source can meet
daytime standard in construction site of 85dB(A); at fitment and structure phase, for
mobile crane, the noise 80m away from the sound resource can meet daytime standard
in construction boundary of 65dB(A); for other construction machinery, the noise 60m
away from the sound resource can meet daytime standard in construction boundary of
70dB(A)
If it is necessary to construct at night time, the noise in construction site shall meet the
requirement of 55 dB(A). At earthwork phase, it shall be 150m away from the sound
resource; at foundation phase, the pile driving works is impermissible at night time; at
other construction phases, it shall be 150m away from the source resource; at fitment
and structure stage, it shall be 200m away from the sound resource; the generator
shall be 260m away from the sound resource.
If the machines used at the phase work at same time during each construction phase,
for earthwork stage, all construction machines shall be kept for 60m away from
construction boundary at daytime and 350m at nighttime so as enable the construction
boundary noise meeting the requirements; at foundation phase, all construction
machines shall be kept 30m away from construction boundary at daytime and the pile
driving works are prohibited at nighttime; at structure phase, all construction
machines shall be kept 150m away from construction boundary at daytime and 350m
at night time so as to enable the construction boundary noise meeting the
requirements.
The summary of main sensitive spots and populations suffered by construction noise

As shown by the field survey, the construction sites of stations in this project are
normally near the sensitive spots of ambient environment and the noise in
construction site is hard to meet the requirements in GB12523-90 Noise Limits for
Construction Site.
(II) Operation period
Nanchang Rail Transit Line 2 phase I project is of underground line type with 1 car
depot and integrated base and 2 main substations. According to the characteristics of
noise source impact, the noise sources impacting external environment in
underground section mainly include ventilation pavilion noise and cooling tower
noise; the lead track and trial run line of car depot and integrated base will generate
the noise impact of train operation; the fixed sound source device in workshop will
also generate certain noise impact; the noises in main substation mainly consists of
the noises of transformer and cooling fan.
(I) Noise of underground station environment control system
(1) Prediction results
A. During non-air conditioning period, the equivalent continuous A sound levels of
each sensitive spot during day time and night time actual operation period are
separately of 52.8 - 72.7dBA and 51.9 - 64.4dBA with the increments of 0 - 6.0dBA
and 0 - 13.2dBA in comparison with the present status. The 15 prediction points at 14
sensitive spots at day time exceed the limits with the over-limit amount of 0.1 8.8dBA and over-limit rate at prediction points of 55.6%; among 25 sensitive spots
during night time operation period, except Liantai Hanlin City (N1) and Jiangxi
Province Revolutionary Memorial Hall (N15), 25 measurement points at other 23
sensitive spots exceed the limit with the overlimit amount of 0.3 - 14.4dBA and
prediction point over-limit rate of 92.6%.
B. During air conditioning period, the equivalent continuous A sound levels of each
sensitive spot during day time and night time actual operation period are separately of
56.9 - 72.7dBA and 52.2 - 67.7dBA with the increments of 0 – 12.6dBA and 0 21.4dBA in comparison with the present status. The 20 prediction points at 19
sensitive spots at day time exceed the limits with the over-limit amount of 0.1 12.8dBA and over-limit rate at prediction points of 74.1%; during night time
operation period, among 25 sensitive spots except Jiangxi Province Revolutionary
Memorial Hall (N15), 26 measurement points at other 24 sensitive spots exceed the
limit with the overlimit amount of 0.3 - 22.7dBA and prediction point over-limit rate
of 96.3%.
The vast majority of sections in this project advances under existing urban road and
the ventilation pavilion area is not far from the road, so most of assessment points are
interfered by road traffic noises and it is general for background noise overlimit. The
traffic noise will be still the main cause after project is built and put into service.
(2) Impact range
During non-air conditioning period (without activation of cooling tower), the noise
standard-reaching protection distances in zones of category 4a, 2 and 1 around
ventilation pavilion are separately of 20m, 38m and 71m; during air conditioning
period, if normal cooling tower is used, the noise standard-reaching protection
distances in zones of category 4a, 2 and 1 around ventilation pavilion are separately of
48m, 90m and 170m; if the low noise cooling tower is used, the noise
standard-reaching protection distances in zones of category 4a, 2 and 1 around
ventilation pavilion are separately of 24m, 45m and 85m.
(3) Population affected
The population in sensitive spots along the line which is directly affected by subway
pavilion and cooling tower noise is about 9,397.
(II) Noise at boundary of car depot and integrated base
(1) During operation period of integrated base, day time environment noise of two
sensitive spots in different prediction years: 58.3 - 58.7dBA; night time operation
period: 45.0 - 45.6dBA; In reference to Sound Environment Quality Standard, the
noise prediction values at these two sensitive spots meet the standard requirements.
(2) the day time noise at boundary of Hongjiaozhou car depot and integrated base
after construction completes is 45.6~60.7dBA and 37.7~54.6dBA in night time
operation period; In reference to category 2 standard in GB12348-2008 Emission
Standard for Industrial Enterprises Noise at Boundary, the east boundary is influenced
by the noise from washing shed with the overlimit amount during night time actual
operation period of 4.6dBA; the west boundary is near the test run line with the day
time overlimit amount of 0.7 dBA; other boundaries in different prediction years
comply with the standard.
(III) Main substation noise
Yangyang Chuntian is about 30m from Qingshan Crossing Station main substation
and the noise level simply affected by the main substation is 33.6dBA. The
environment noise prediction value maintains the present status without any
increment.
4.1.2 Predictive Assessment of environment vibration
(I) Construction period
The construction machinery of this project is mainly of vibration type operation,
including the vibrations from shield machine, construction works such as pile driving
and excavation, and transport and handling of transport vehicles, so the construction
works inevitably impact the along-line traffic, buildings and residents livings.
As shown by the field survey, the locations affected by construction machinery
vibration are mainly of environment sensitive spots near the station (see table 5.4-6 in
the report). Most of the construction sites of this project are located in urban built-up
area and near the resident housing, so part of sensitive spots is hard to meet the limit
requirements of GB10070-88 Standard of Vibration in Urban Area Environment and
the construction machinery vibration inevitably impacts the sensitive spots around
construction sites. The section tunnel adopts shield method construction with less
vibration effect on ground surface at both sides of line and certain impact on vibration
right above the line, which is mainly of ground settlement.
(II) Operation period
（1） Assessment and analysis of ambient vibration prediction results
After project construction, the vibration values VLz10 of 110 environment sensitive
spots and 161 prediction points along the line is 57.5~80.8dB at day time with
increment 1.1~26.6dB to present status and 56~80.8dB at night time with increment
of 3.7~30.6dB to present status. The ambient vibrations of 32 sensitive spots along the
line exceed the standard requirements. The over-limit amounts at day time and night
time are separately of 0.1~5.8dB and 0.1~8.8dB with the over-limit ratio of 29.0%.
In 18 sensitive spots including Jinxing Yuan, Jiangxin International Garden, Honggu
Kaixuan and Yangming Road No.319-381, there are 35 prediction points. The ambient
vibration prediction values at day time and night time of prediction point in “both
sides of traffic arterial road” are sepately of 62~80.8dB and 61.7~80.8dB; in reference
to GB10070-88 Standard of Vibration in Urban Area Environment, three sensitive
spots at Changbei Post Office (Changbei Post Office dormitory), Honggu Kaixuan
and Honggu Kaixuan nursery school exceed the limits with the day time over-limit
amount of 0.1 - 5.8dB and night time over-limit amount of 3.1 - 8.8dB. The ambient
vibration prediction values at day time and night time of prediction point in second
row building in “residential and culture education area” are of 60.7~69.0dB and
60.3~68.9dB; in reference to GB10070-88 Standard of Vibration in Urban Area
Environment, 2 sensitive spots of Honggu Kaixuan and Jiangxi Provincial Public
Security Department staff dormitory exceed the limit, and their ambient vibration
values at day time meet the standard requirements while the over-limit amount at
night time are separately of 1.5 dB and 1.9dB.
There are 12 prediction points at 11 sensitive spots including Yuantou Xiaojia,
Fuxiang Zhujia, Wangjia and Yinghua Foreign Language School are in “mixing area,
CBD” area and their ambient vibration prediction values at day time and night time
are separately of 63.5~79.8dB and 63.3~79.8dB; in reference to GB10070-88
Standard of Vibration in Urban Area Environment, three sensitive spots of Yuantou
Xiaojia, Fuxiang Zhujia and Fuxiang Wangjia exceed the limits with the day time
over-limit amount of 0.1 - 3.4dB and night time over-limit amount of 0.2 - 6.4dB.
There are 81 sensitive spots including Fandun Residence, Jiangxin International
Garden and Fenghe Xincun and 112 prediction points are in “both sides of traffic
arterial road” area, and their ambient vibration prediction values at day time and night
time are separately of 57.5 - 80.0dB and 56.0 - 80.0dB. In reference to GB10070-88
Standard of Vibration in Urban Area Environment, 25 sensitive spots including
Shajing community, Jiangxi Province Traffic Technical School staff dormitory and
Nanchang Bairui Lijing Hotel exceed the limits with the day time over-limit amount
of 0.7~5.0dB and night time over-limit amount of 0.1~8.0dB.
（2）Prediction results and analysis of vibration speed
Along this project the maximum speed response values of culture relic structures at
three locations of Jiangxi Hotel, Jiangxi Federation of Literary and Art Circles (Sino
Soviet friendship Hall) and Jiangxi Province Exhibition Center (former Mao Zedong
Thought Victory Long-live Site ) exceed the standard requirements with the over-limit
amounts separately of 0.14mm/s, 1.35mm/s and 1.07mm/s.
(3) Prediction results and analysis of secondary structure noise
The indoor secondary structure noise of 38 sensitive buildings within the range of
10m from right above project underground section to outer rail centerline is between
34.5 and 47.4dB; in reference to reference standard limit of “40dB(A)”, there are 29
sensitive spots affected by the secondary structure noise from subway vibration with
the over-limit amount of 0.1~7.4dB.
4.1.3 Predictive Assessment of Air Environment
(I) Construction period
Sine most of the construction sites are near the traffic roads, the construction
machines and transport vehicles with the fuel as power source emit certain amount
of exhaust near the construction site. Although the total amount of exhaust emission in
the region increases, it will not impose remarkable impact on ambient air environment
as long as to strengthen the servicing of devices and vehicles, ensure no emission of
soot not completely combusted and strictly comply with the regulations on motor
vehicles in Nanchang city.
The excavation and drilling on dry ground surface may generate the fine dust; in
addition, after the original vegetation is destroyed during construction period, the
ground surface is exposed with water evaporated and forms the dry and loose particles,
and it will generate the raise dust in case of large wind or backfilling. A part of fine
dust floats in the air and the other part drifts to nearby ground and building surface
with the wind. The fine dust pollution during construction has large harness. If the
fine dust floating in the air is inhaled by the construction staff or surrounding
residents, it will lead to various respiratory diseases, and may also heavily impact the
healthy because the fine dust carries large amount of pathogenic bacteria; the flying
fine dust will also reduce the visibility and may lead to traffic accident; the fine dust
drifting on various buildings and tree leaves may impact the landscape.
The impact duration of secondary raise dust from transport vehicle is the longest and
the impact degree will significantly increase for the damage of road surface and mud
explosion in construction site. It is predicted that the raise dust quantity depends on
road surface dust deposition amount under constant vehicle speed and weight. The
larger the dust deposition amount, the heavy the secondary raise dust. Since the
transported construction materials in this project are mainly of underground deep
spoil with certain humidity, so the raise dust generated by the construction transport
vehicles in this project will only influence the residents near the construction site,
especially the residents in first row of buildings.
(II) Operation period
(1) Impact analysis of exhaust odor of ventilation pavilion during operation period
According to the station plan in feasibility study design, carry out field survey for
ambient environment of all ventilation pavilions of the project, and finally determine
there are environment sensitive spots at 20 ventilation pavilion areas in 13 stations
and 50m range of 1 sectional ventilation pavilion 50m. The impact analysis results of
subway exhaust pavilion exhaust odor on sensitive spots refer to table 4.1-2.

(2) Prediction and analysis of exhaust pollutant emissions in integrated base shunting
locomotive
The traction type of this project is of electric locomotive, so there is no exhaust
emission of locomotive. In design, the Hongjiaozhou car depot & integrated base is
equipped with 2 shunting locomotives (diesel locomotive for line inspection & repair
and locomotive rescue). The shunting locomotive emits small amount of exhaust
pollutants. According to emission coefficient method, the emission prediction of
exhaust pollutants for Hongjiaozhou car depot & integrated base shunting locomotive
refer to table 4.1-3.

As shown in table 4.1-4, after operation of rail transit, the Automobile exhaust
pollutant emission reduction amounts of CO, CHX and NOX from substitution for bus
traffic at initial phase are separately of 263.8, 88.9, 569.3t/a and these reductions will
be more at short term and long term. So the rail transit construction not only changes
the traffic structures, increases the passenger transport volume, relieves the ground
traffic congestion and more rapid and comfortable than bus, but also it reduces the
exhaust pollution emission of bus transport and benefits the improvement of
Nanchang urban environment air quality. The rail transit is one of effective approach
to solve the urban traffic pollution.
4.1.4 Predictive Assessment of Water Environment
(1) The domestic sewage, muddy water and other production wastewater generated
from construction stations, car depot and other sites are reused or drained into urban
pipeline network after treatment of sedimentation tank, and will not affect the surface
water and underground water environment.
(2) The sewage amount from Hongjiaozhou car depot and integrated base is 214 m3/d,
in which the sewage reuse amount is 95m3/d and sewage discharge amount is 119
m3/d. The total discharge amount of domestic sewage in stations along the line is
160m3/d. The overhaul sewage of car depot integrated base after treated by oil
separation tank, and the car washing sewage after treatment of matching
neutralization - sediment – filtration by car washing device, are reused, and the
normal domestic sewage is treated by septic tank. The domestic sewage of station is
treated by septic tank. The above sewage can be discharged into existing or planned
municipal sewage pipeline and then into municipal sewage treatment plant. The
drainage water quality can meet the requirements of level 3 emission standard in
GB8978-1996.
(3) The present water quality of river section for Ganjiang River Bayi Bridge is good
and classified as category III; Yudai Rover is polluted by urban domestic sewage
drainage with the present water quality of category V. The main water quality indexes
of underwater of this line meet the requirements for category III water quality in
GB/T14848-93 Standard for Underground Water Quality.
(4) The project passes under, in tunnel form (shield construction method), drinking
water source class 1 protection zone waters and land area range of Ganjiang River
Changling Water Plant and Niuhang Plant, and drinking water source class 2
protection zone waters and land area range of Shuangang Water Plant. There is no
ground surface works in water source protection zones. By strengthening the
environment management during construction period, the engineering construction
will not directly impact on the water quality at water source and water intake. The
project does not involve any underground drinking water resource protection zone.
(5) During engineering construction, if the pollutants such as oil flow into the
underground water, it may affect the underground water quality in the area to some
extent. Provided that the full construction process is scientifically, reasonably and
orderly managed, the impact of construction on underground water quality can be
minimized. The project will not impact the underground water quality during
operation period.
(6) The engineering construction adopts underground diaphragm wall or cast-in-place
pile fence and the auxiliary retaining structure adopts cast-in-place pile fence with jet
grouting pile for waterproof so as to effectively control the ground settlement.
(7) The urban sewage infrastructures along the line are complete and the construction
sewage quality is simple. The assessment considers the sewage will not pollute the
underground water quality if treated with proper process and collected into nearby
municipal pipeline network or waters.
(8) The areas of this project are located at both banks of rivers such as Ganjiang River
and Fuhe River, and aquifer is of sand gravel strata and the underground water
complements the surface water. The short term falling of local underground water
level during construction period will rapidly recover after rainfall completed, and will
not affect the underground water resource in the area.
4.1.5 Predictive Assessment of Ecological Environment
This project is located at Nanchang urban area, the areas passed by this project take
human activities as the core, there are row upon row of office buildings, stores,
residential buildings and Party and government organizations, which is artificial
ecosystem based on urban structure; areas around starting point of the line,
High-Speed Passenger West Railway Station and Longgang Station are mainly
farmland and wasteland, and ecosystem type is farmland ecosystem.
There is no nature reserve, scenic spot or forest park in the assessment scope, and
there are few farmlands only near Fuxiang Zhujia Village at the starting point of this
line.
Influences of the project on the ecological environment are the followings:
(1) The project does not involve any ecological sensitive area such as natural reserves,
scenic spot and basic farmland conservation area.
(2) After construction and operation of this project, it will enhance the connectivity of
all function block landscapes along the line, keep the smooth input/out operation
between the function blocks, ensure the high efficiency operation of city, enhance the
stability of urban landscape ecological system and ensure the healthy development of
city.
(3) According to the landscape aesthetics analysis and analog survey analysis, if fully
considered the unique historic city property of Nanchang city and land use pattern and
adopted the design with blending method and hidden method, it can keep the
coordination of ground buildings such as station entrance/exit and ventilation
pavilions with ambient environment.
(4) The construction of rail transit has remarkable advantages in saving of land
resource and energy, and in favor for integration and modification of Nanchang land
resources, relief of regional land utilization pressure and improvement of land
utilization efficiency.
4.1.6 Predictive Assessment of Solid Wastes
(1) The solid wastes during construction period are normally of spoils generated
during construction period. The total spoils quantity in stations and open cut sections
of this project is 2.4344 million m3, and total spoils quantity in shield section is
0.9075 million m3, and the total spoils quantity of car depot is 414,200 m3. The spoils
generated from line 2 are planned to transport to Yaohu repair depot project
department spoil field and Jiaolong car depot spoil field for backfilling treatment.
(2) The solid wastes during operation period are mainly of station and car depot
domestic garbage. According to analog survey data, it is predicted the total discharge
amount of solid wastes during operation period of this project is 860 - 1370t/a. The
wastes at each station are collected by environment sanitation workers and
collectively delivered to urban garbage treatment field for treatment, so there is only
slight impact on environment.
(3) The waste oil and dreg from sewage treatment plant in car depot & integrated base
during operation period, clothes wiping the oil in each procedures, waste transformer
oil are of hazardous wastes, and shall be entrusted to the agency with related
qualification for harmless treatment; the battery regularly replaced shall be reclaimed
by the manufacturers and the anti-seepage treatment shall be conducted in battery
deposition room to avoid leakage. So the soil wastes have little impact on ambient
environment by the solid waster generated after operation of rail transit.
(4) Explicitly prohibits the procurement of equipment containing polychlorinated
biphenyls material in transformers and other equipment in the design and tender
documents.
4.1.7 Predictive Assessment of Electromagnetic Environment
The impact of this project on electromagnetic environment mainly includes: random
ignition interference generated from the discharge gap due to poor contact between
vibration or sliding plate and catenary when the EMUs travels on access line of
vehicle integrated base; electromagnetic interference resulted from electromagnetic
induction of substation due to high voltage or large current. The existing environment
assessment indicates that the electromagnetic interference only imposes slight impact
in certain distance with the civil television reception without any impact on human
health.
The report indicates: ①The ground line train traveling may impose certain impact on
the TV user with antenna to receive signal, but most of the channels can be normally
displayed. Since the cable TV connection rates at sensitive spots of this project are
high, it is predicted the radio interference from project construction will only affect
the teleview quality of 28 households which do not connect the cable TV network. So
this assessment reserves compensation of 500 Yuan for each household for their
connection with wired CCTV and the total cost is 14,000 Yuan. ② The main
substations of Xuefu Avenue and Medical College are constructed on ground.
According to analog analysis, the generated power frequency electric field and
magnetic field are low and comply with the limits of power frequency electric field of
4kV/m and power frequency magnetic field of 0.1mT recommended in HJ453-2008
Technical Guidelines for Environment Impact - Urban Rail Transit.
4.1.8 Predictive Assessment of Social Environment
Whether in construction period or operation period, this project will affect the livings
of Nanchang citizens in different degrees and from various aspects. The positive
effects lie in that the project construction will provide Nanchang people a more rapid,
convenient and environment protection public transit facility and Nanchang rail transit
line 2 during operation period will become a more convenient, safe, comfortable and
economic communication mean for the residents along the line; at same time, the
project construction works and enclosure will inevitably bring forward adverse impact
on the people along the line; however the adverse impact is controllable and
temporary as long as implemented related relief measures in the report.
The positive effects also include followings: the barrier free access benefits the
traveling of disables; the increase of female toilet proportion enhances the female
social position and living convenience; the reasonable ticket fare is in favor of the
low-incoming group and equivalent to increase of economic income; the rail transit
line 2 improves the urban traffic after operation and brings forward favorable impact
on land utilization change an therefore promote the implementation of development
construction and planning of city.
The adverse impacts are mainly in construction period and include followings: the
station enclosure impacts the local urban traffic; station construction enclosure
imposes temporary impact on incoming of surrounding merchants; the construction
enclosure leads to inconvenient livings of nearby residents and increases their
traveling time; noise and vibration disturbance due to construction machinery
operation, construction raise dust, sewage, muddy water, deposition and transport of
construction garbage and construction materials will affect the living quality of
residents; the ground settlement and vibration affect the ground building stability
during construction period.
4.1.9 Cumulative Impact Assessment
The cumulative impact generated by the project is mostly incarnated at the
enhancement of water loss and soil erosion volume owing to the spoil ground set for
Line No. 1 and Line No. 2; the transfer station is long in construction period and large
in floor space, which will bring cumulative impact to the surface traffic; value of
noisiness at the sensitive spot will be increased under the combined action of several
environmental control equipments in the transfer station; the transfer station is long in
construction cycle and large in cut area, therefore the soot will cause cumulative
impact to air if it is not treated properly; the cumulative impact caused by large scale
of the transfer station and discharge amount of product waste; the impact of transfer
station construction to living of residents and income of shops around.
4.1.10 Environmental Risk Impact Assessment
(1) Risk during construction period mainly occurs during digging of base pit or
interval tunnel. Improper selection of construction methods tends to cause uneven
settlement, ground collapse or bulging; Accidents such as collapse, roof fall, sand
gushing water gushing, and water transmission etc. tend to happened during
construction due to influences by multiple factors such as geological and hydrological
factors etc.; Improper selection of construction methods and retaining program will
cause breakage of adjacent underground pipelines or cracking, leaning or even
collapse of surrounding constructions. Major risk source during operational period:
The major risks and accidents during operational period come from social hazards
such as arson or terrorist attack etc., and the accidents due to improper operation by
staff and mechanical failure etc.. The aforesaid accidents have not only caused huge
economic losses and tend to cause personal casualty and significant social influences.
(2) The section across Ganjiang River of No. 2 subway line of
Nanchang(YAK33+850~YAK35+400), and the international sport center station,
Wolongshan station, Lingbeisanlu station, Qianhu Avenue station, Xuefu Avenue
station, Cuiyuan Road station, Subway Building station, Yayuan Road station,
Hongguzhong Avenue station, Tengwangge station, Yangming Park Station, Qingshan
Road station, Fuzhou Road station, Bayi Square station, Yongshu Road station and
Hongdu Central Avenue station belong to section with complex geological conditions,
and there is a high possibility of geological disasters(mainly instability of tunnel
surrounding rock and base pit slope, water inrush in base pit and water gushing in
tunnel etc.) caused and aggravated by engineering construction, thus relevant
engineering measures and preventive methods shall be adopted for treatment.
Meanwhile, the subway station is constructed by means of opening digging and
semi-cover digging, and extraction and drainage of a large quantity of underground
water in base pit tends to cause sudden decrease in underground water level and
drifting sand, regional ground settlement and collapse, and deformation and cracking
etc. of surrounding buildings. As the project runs across the fracture zone F2 under
Ganjiang River, there is possibility that massive water inrush may happen after
completing digging of the tunnel due to water transmission in the fracture zone. The
project runs across bridges and piles of approach bridge of Bayi Bridge, Fenghe
overhead bridge, and Laofushan overhead bridge etc., rails of Nanchang Railway
Station, residential buildings, and tends to cause settlement and deformation of the
aforesaid buildings or structures, and many overturn the structures and endanger
safety in serious cases.
4.1.11 Residents relocation and Resettlement Impact Assessment
(1) Resettlement for No. 2 rail transit project of Nanchang City under the loan of
World Bank is mainly related to dismantlement of the resident’s housed due to
construction of subway depots and stations, involving 1,043 individual families and
influencing 4,001 persons. 142 persons and 31 households will be influenced due to
land requisition for construction of subway depots. Resettlement at various stations
involves 22 enterprises and units, and 201 shops will be resettled, involving 858
employees of the shops.
(2)Certain economic losses will be caused to the aforesaid units, shops and
individuals due to land requisition and resettlement for the project, which will
influence their life and employment as well. The major environmental impacts caused
during resettlement are rubbish and dust caused by house dismantlement. Certain
impacts will be caused on vegetation due to resettlement, which will also cause noise
as well.
(3) The major measures to reduce impacts on resettlement in the report are as follows:
Resettlement Office of Nanchang Rail Transit Co., Ltd. has held joint conference
attended by various consultancy units and designing units during project planning and
design to adjust and optimize the project design program and reduce the quantity of
resettlement and land requisition. Make out compensation and reward program for the
personal households with resettled houses, the families influenced by land requisition,
and the enterprises, units and shops influenced by resettlement, and the employees of
the shops influenced during resettlement. Feedback mechanism for public opinion
has been formulated to lower the social impacts caused by resettlement. The
environmental impacts caused by resettlement are reduced through rational
arrangement of construction plan and traffic organization and design, water sprinkling
to reduce dust and strengthening vibration and noise reduction measures during
project construction.
4.1.12 Material and Cultural Resources Impact Evaluation
The line assessment range in this project involves 4 historic and culture sites to be
protected of Zhu De Officer Educational Group Site, former Mao Zedong Thought
Victory Long-live Site, Aug. 1 Nanchang Uprising Memorial Tower and Xiong Shihui
Residence and 3 historic and culture buildings to be protected of Jiangxi Hotel, Sino
Soviet friendship Hall (Jiangxi Federation of Literary and Art Circles) and Jiangxi
Province Revolutionary Memorial Hall. The project does not involve the protection
scope of above mentioned historic and culture sites to be protected and buildings to be
protected. Except No.4, 7 and 7 station entrance/exit for August 1st Square Station
intrude into the construction control zone of “former Mao Zedong Thought Victory
Long-live Site” and No.10 entrance/exit and ventilation pavilion intrudes into the
construction control zone of “Aug. 1 Nanchang Uprising Memorial Tower”, and the
project does not involve the construction control zone range of other sites and
buildings to be protected.
The project is complete of underground line and is laid out basically along the
existing urban roads in the culture relic area passed. The project design program, by
optimization at project route selection phase, evades from the protection range of Mao
Zedong Thought Victory Long-live Site and be allocated out of the construction
control zone range of Aug. 1 Nanchang Uprising Memorial Tower; the project adopts
shield method for construction and the section construction basically will not damage
the environment scenes of historic and culture sites to be protected.
During construction process, if any culture relic and ruin is found, it is necessary to
immediately stop the construction and take protective measures such as blocking the
scene, and report to Nanchang city culture relics administrative department which will
be responsible for the excavation of culture relics and ruins with reasonable measures,
and then the engineering construction can continue.Establish vibration monitoring
mechanism during operation period to strengthen the long term tracing and
monitoring for the vibration effect which may generate during subway operation
period. Through intensification of the vibration protection measures during
construction period and operation period, ensure the engineering construction and
operation will not adversely impact the structure safety of buildings.
For the old trees and famous wood species involved along the line, control the
excavation face of underground works and intensify the tree root protection and
environment protection measures during construction period so that the engineering
construction has no adverse effect on them.

Solution
1. The main soil layers in station foundation pit range are
mainly of medium weathering argillaceous siltstone which
is of soft rock. The softening characteristics may lead to
rock strength variation and strength reduction. At same
time, its own steadiness is poor and it will soften and
disintegrate if exposed to the water for long term, and
therefore lead to adverse impact on foundation evenness
and foundation pit stability.

6.2 Analysis of Economic Gains and Lossed due to Environmental
Impacts
Analysis of economic gains and losses due to environmental impacts is mainly
intended to measure the environmental protection effect that can be achieved through
the environmental protection investment to be input for the construction project, and
make general economic assessment of environmental impacts through comprehensive
calculation of economic losses caused by factors of environmental impacts, benefits
of environmental protection measures and engineering environmental benefits. Thus
in addition to calculating investment and expenses for controlling pollution, the
possible environmental and economic effects shall be accounted during analysis of
economic gains and losses due to environmental impact.
6.2.1 Means of Assessment and Analysis
The economic gains and losses due to environmental impacts of the project are
comprehensively assessed by means of static analysis method, and conclusion is
drawn from environmental and economic perspectives.
(1)Net Benefits of Environmental Protection Investment
Calculation of net benefits of environmental protection investment is intended to
assess the dominant environmental impacts of the project(beneficial or adverse
impacts). The calculation formula is as follows:
B 总=(B 措-K)+B 工–L 前:
As shown in the formula：B 总: Net benefits of environmental protection investment;
B 措: Environmental economic benefits produced by environmental
protection investment;
K : Environmental protection investment and expenses;
B 工: Environmenal and economic benefits due to environmental
impacts of the project;
L
前
: Environmental and economic lossed in case of no
environmental protection funds
(2)Investment Efficiency Ratio in Environmental Protection
The benefits and expenses ratio of investment on environmental protection must be
calculated to assess the rationality of investment on environmental protection, and
feasibility of environmental protection. The calculation formula is as follows:
E 总=(B 措+B 工–L 前)/K
In case E 总≥1, it shows that the environmental economic benefits of the project are
larger than the environmental protection expenses, and the project is accpetab le. In
case E 总<1, it shows the environmental protection expenses of the project is larger
than the benefits obtained, and the project shall be given up. The larger E 总 is, the
better effect of environmental protection investment will be.
(3) Ratio between Environmental Protection Investment and Capital Construction
Investment
Comparison of the index with that of similar domestic projects can confirm the
rationality of the project.
6.2.2 Analysis of Economic Gains an Losses due to Environmental Impacts
The economic gains and losses due to environmental impacts of the project are
comprehensively assessed by means of static analysis method, and conclusion is
drawn from environmental and economic perspectives.
(I) Major Factors Influencing Environment
The major factors influencing environment entered into analysis of economic gains
and losses due to environmental impacts are noise, ecological landscape and water
pollution etc. according to characteristics of the project and specific local
environmental conditions:
(II) Environmental economic losses produced before input of environmental
protection funds L 前
(1) Environmental economic losses caused by noise: L 前声
According to the characteristics of the project, the populations around the air kiosk,
cooling tower and depots as well as the ground lines of entrance/exit depot will be
influenced by noise to various extents. Thus the project mainly assesses the
environmental economic losses caused to surrounding populations due to subway
noise. The report has selected the assessment coefficiency for environmental and
economic lossed caused by noise of rail transit in Germany to passengers adopted by
Planco in 1992 in a similar case, i.e. RMB 1.2 yuan per 100 persons km.
Suppose the average running speed of the train is 35km per hour(daily operational
hour: 18 hours). As rail transit is a rapid means of transport, if the short interval
between the trains is omitted, the trains running on the route can be seen as
continuous, and the social populations around the noise source will receive constant
impacts by the noise. And such people are influenced by the noise as if they travel by
subway at 35km per hour for 18 years. It is estimated 9397 persons will be influenced
by the noise of the project, and L 前声 is 22 million yuan per year.
(2) Environmental economic losses(L 前水) caused by water pollution:
If the sewage discharged by the project is directly discharged without being disposed,
the receiving water body will be polluted, and environmental economic losses will be
caused due to deterioration of water quality. Such environmental economic losses is
approximately replaced by the sewage discharge expenses payable for discharge of
sewage of the same water quality and quantity. According to the current charging
standards and provisions of relevant department, in case the sewage produced by the
project is directly discharged without being disposed, the construction unit will pay
150,000 yuan per year as the sewage discharge expenses. Thus L 前水 is 150,000 yuan
per year.
(3)Total environmental and economic losses(L
environmental protection funds:
前
) caused before input of
Environmental and economic losses caused before input of environmental protection
funds: L 前= L 前声+ L 前水=22.15 Million yuan per year
(III) Investment on Environmental Protection K
The investment on environmental protection of the project is 131,644,000 yuan,
which will be amortized over 4.25 years. Thus K is 30,975,100 yuan.
(IV)Environmental economic benefits(B 措) caused by investment on environmental
protection:
(1)Environmental economic benefits(B 措声) caused due to decrease in the number of
people influenced by noise after noise control
According to the prediction results for impacts on sound environment, the noise level
at the sensitive points along the project line is basically maintained at the level before
project construction after noise and pollution prevention and control measures are
taken, that is the project construction will not increase the noise level of various
sensitive points. B 措声 is 22 million yuan per year.
(2) Environmental economic benefits(B 措水) caused by control of water pollution:
According to relevant provisions, the sewage of the project will be discharged after
reaching standard through treatment. The sewage discharge fee in the amount of
30,000 yuan per year shall be paid after sewage treatment through calculation, and
150,000 yuan per year shall be paid before sewage treatment. Thus the environmental
economic benefits produced through treatment of water pollution(B 措水 ) is 120,000
yuan per year.
(3) Total environmental economic losses produced by investment on environmental
protection(B 措):
B 措= B 措声 + B 措房 + B 措水 =22.12 Million yuan per year
(V) Environmental economic benefits caused by engineering environmental
impacts(B 工):
The extent of environmental pollution will be different in case road traffic instead of
rail transit is adopted to meet the ever increasing demands for traffic by economic and
social development along the route of the project in Nanchang City.
(1)Comparison of Environmental Economic Losses due to Noise Pollution:
To compare the environmental economic losses casued by noise due to two means of
transport, the function of road traffic shall be the same as that of the means of
transport of the project, and the travelling speed per hour is 35km per hour, with the
daily operational period being 18 hours and the same quantity of passengers.
Moreover, as road traffic is totally on the ground, the number of people influenced by
noise on the two sides of the traffil route will be larger than that of subway, and is
estimated to be 24,000. The populations along the road are influenced by noise as if
they travel by road at the speed of 35km per hour for 18 hours.
According to relevant data of Germany, the estimation coefficient for environmental
economic losses caused by road traffic noise on the passengers is RMB 1.7 yuan per
100 persons km.
The environmental economic losses caused by road traffic noise(L 路声) is 80 million
yuan per year through calculation.
The environmental economic benefits(B 工声) caused by noise pollution in the two ways
is B 工声= L 路声- L 后声=80 Million yuan per year.
(2)Comparison of Environmental Economic Losses due to Atmospheric Pollution:
As rail transit utilizes power as energy, it produces less atmospheric pollution, thus the
environmental economic losses caused by its atmospheric pollution is approximately
0.
According to the conclusion of atmospheric environmental impact assessment, the
emission of automobile exhaust will be reduced due to project construction. The
environmental economic losses due to road atmospheric pollution is estimated
according to the environmental economic losses caused by the road traffic exhaust on
passengers in Germany, that is RMB 0.2 yuan per 100 persons km. B 工气=9.8 Million
yuan per Year.
(3)Total environmental economic benefits(B 工) due to engineering environmental
impacts:
B 工= B 工声 + B 工气 =89.8 Million yuan Per Year
(VI) Analysis of Economic Gains and Losses due to Environmental Impacts:
(1) In case B 总 is larger than 0, it shows the environmental impacts of the project are
mainly beneficial.
Net benefits from environmental protection investment B
=58,294,900 yuan per year.
总
=(B
措
-K)+B

-L
前
(2) Environmental protection investment efficiency E 总=(B 措+B 工-L 前)/K=2.92
E 总>1, which shows that the environmental economic benefits of the project is larger
than the environmental protection expenses, and the environmental protection
investment effect is good.
(3)Environmental protection investment/capital construction investment ratio:
The environmental protection investment of the project is 131,644,000 yuan, and the
estimated total investment of the project is 14,846,032,400 yuan, thus the
environmental protection investment/capital construction investment is 0.87%, which
is similar to that of the environmental protection investment of similar domestic
project. Thus the environmental protection investment is rational.
6.2.3 Conclusion:
The completion and operation of the project will positively promote social economy
and urban environment in areas along the routes of the project. The environmental
economic losses caused by project construction will be controlled within a small
scope after several environmental protection measures are taken. Project construction
will produce significant social benefits and environmental benefits, which complies
with the principle of simultaneous growth of economic benefits, social benefits and
environmental benefits.
6.3 Sources of funds
According to the current financial strength of Nanchang, the capital of Nanchang rail
transit line 2 phase 1 project to be considered the mode of direct government
